Hola
Algo como esto
session_start(); // start session
if(!isset($_SESSION['login'])){
if IsEmpty(session("login")) = True then
echo "<b>Welcome!</b><br>Log in. <a href='enter.html' target='_self'>Click here.</a> o <a href='../rg.html' target='_parent'>Register</a>";
Response.Write "<b>Welcome!</b><br>Log in. <a href='enter.html' target='_self'>Click here.</a> o <a href='../rg.html' target='_parent'>Register</a>"
} else {
else
echo "<b>Hello</b> ".$_SESSION['login'];
echo "<br><a href='exit.php' target='_self' onclick='reloadPage()'>Log out</a>";
Response.Write session("login")
Response.Write"<br><a href='exit.php' target='_self' onclick='reloadPage()'>Log out</a>"
}
end if
Suerte
